The best-benchmarked open-source AI memory system.

What's new

The best-benchmarked open-source AI memory system.

Key details

• Verbatim storage, pluggable backend, 96.6% R@5 raw on LongMemEval — zero API calls.
• MemPalace has no other official websites.
• The only official sources are this GitHub repository, the PyPI package, and the docs at mempalaceofficial.com.
• Any other domain (including .tech, .net, or other .com variants) is an impostor and may distribute malware.

Results & evidence

• Verbatim storage, pluggable backend, 96.6% R@5 raw on LongMemEval — zero API calls.
• Important Claude Code sessions expire in 30 days without auto-save hooks wired.

Limitations / unknowns

• Generalization outside curated tasks is still unclear.

Next-step validation checks

• Reproduce one claim with a public baseline and fixed evaluation settings.
• Check robustness on out-of-distribution or long-context cases.
• Track whether independent teams report matching results.

• This repository is closer to a museum exhibit than a product pitch, a crustacean-run artifact kept alive by clawed gajaes, swept and labeled by agents, and automatically maintained according to the harnesses above.
• As already described in the project philosophy, this is not meant to be hand-operated like a normal product repo.
• It is an agent-managed exhibit: the harnesses plan, execute, verify, label, and preserve the artifact while the crabs keep the tank running.
